WARNING
■To ensure the system can operate properly
Blind Spot Monitor sensors are installed behind the left and ri ght sides of the
rear bumper respectively. Observe the following to ensure the Blind Spot
Monitor can function correctly.
● Do not subject a sensor or its surrounding area on the rear bumper to a
strong impact.
If a sensor is moved even slightly off position, the system may malfunction
and vehicles may not be detected correctly. In the following si tuations,
have your vehicle inspected by your Toyota dealer.
• A sensor or its surrounding area is subject to a strong impact .
• If the surrounding area of a sensor is scratched or dented, or part of them has become disconnected.
● Do not disassemble the sensor.
● Do not attach stickers or install accessories to the sensor or surrounding
area on the rear bumper.
● If a sensor or the rear bumper needs to be removed/installed or replaced,
contact any authorized Toyota retailer or Toyota authorized rep airer, or any
reliable repairer.
● Do not modify the sensor or surrounding area on the rear bumper .
● Do not paint the rear bumper any color other than an official Toyota color.
●Keep the sensors and the surrounding
areas on the rear bumper clean at all
times.
If a sensor or its surrounding area on
the rear bumper is dirty or covered with
snow, the Blind Spot Monitor may not
operate and a warning message ( P.
271) will be displayed. In this situation,
clear off the dirt or snow and drive the
vehicle with the operation conditions of
the Blind Spot Monitor ( P. 275) satis-
fied for approximately 10 minutes. If the
warning message does not disappear,
have the vehicle inspected by your Toy-
ota dealer.

Blind Spot Monito
r detection areas
The areas that vehicles can be detected in are outlined below.
The range of each detection area is:
Approximately 1.6 ft. (0.5 m) to 11.5 ft. (3.5 m) from either s ide of
the vehicle
*
*
: The area between the side of the vehicle and 1.6 ft. (0.5 m) from the
side of the vehicle cannot be detected.
Approximately 3.3 ft. (1 m) f orward of the rear bumper
Approximately 9.8 ft. (3 m) from the rear bumper
Approximately 9.8 ft. (3 m) to 197 ft. (60 m) from the rear
bumper
*
*
: The greater the difference in speed between your vehicle and the
detected vehicle is, the farther away the vehicle will be detec ted, caus-
ing the outside rear view mirror indicator to illuminate or flash.
WARNING
■ Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The Blind Spot Monitor is a supplementary function which alerts the driver
that a vehicle is in a blind spot of the outside rear view mirr ors or is
approaching rapidly from behind into a blind spot. Do not overl y rely on the
Blind Spot Monitor.
As the function cannot judge if it is safe to change lanes, ove r reliance could
lead to an accident resulting in death or serious injury. As the system may
not function correctly under certain conditions, the driver’s o wn visual confir-
mation of safety is necessary.

Buzzer operation and di
stance to an obstacle
A buzzer sounds when the sensors are operating.
● The buzzer sounds faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the
obstacle, the buzzer sounds continuously: Approximately 1.2 ft.
(35 cm).
● When 2 or more obstacles are detected simultaneously, the
buzzer system responds to the nearest obstacle. If one or both
come within the above distances , the beep will repeat a long
tone, followed by fast beeps.
Approximately 2.0 ft. (60 cm)
Approximately 4.9 ft. (150 cm)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect obstacles
that are extremely close to the
vehicle.
The range of the sensors may
change depending on the shape of
the object etc.

Situations in which the syst em may not operate properly
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect objects. Particular instances where this
may occur are listed below.
● There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
● A sensor is frozen. (Thawing t he area will resolve this problem .)
In especially cold weather, if a sensor is frozen the sensor di splay may be
displayed abnormally, or objects, such as a wall, may not be detected.
● On an extremely bumpy road, on an incline, on gravel, or on grass.
● When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle
● A sensor is coated with a sheet of spray or heavy rain.
● If objects draw too close to the sensor.
● When a pedestrian is wearing clothing that does not reflect ult rasonic waves
(ex. skirts with gathers or frills).
● When objects that are not perpendicular to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the d etection range.
● Strong wind is blowing
● When driving in inclement weather such as fog, snow or a sandst orm
● When an object that cannot be detected is between the vehicle a nd a
detected object
● If an object such as a vehicle, motorcycle, bicycle or pedestrian cuts in front
of the vehicle or runs out from the side of the vehicle
● If the orientation of a sensor has been changed due to a collis ion or other
impact
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
● If the front of the vehicle is raised or lowered due to the car ried load
● If the vehicle cannot be driven in a stable manner, such as whe n the vehicle
has been in an accident or is malfunctioning
● When a tire chains, compact spare tire or an emergency tire pun cture repair
kit is used
●
When a sensor or the area around a
sensor is extremely hot or cold.
